The Thunderbolt 4 Docking Station with DisplayLink provides these approximate speeds:

• Up to 40 Gbps on the Thunderbolt 4 port
• Up to 10 Gbps on the USB-A 3.2 Gen 2 ports
• Up to 312 MB/s (UHS-II) on the SD card reader

Bandwidth is shared across the dock, so when several Thunderbolt devices are connected at once, the available speed for each can be affected depending on the devices in use.
